PLOW ATTACHMENT.

To ZZ whom it may concern:

Be it known that I, SAM 'PINKNEY D on- KINS, a citizen of the UnitedStates, residing at Saluda, in the county of Saluda and State of SouthCarolina, have invented certain new and useful Improvements in PlowAttaehments; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanyingdrawings, and to the .letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to plows. It has for its object to provide a bed orshoe adapted to support a detachable and replaceable.

plow point or blade, either of the shovel, half shovel, or othertype;and also a standard or stock of any-suitable approved type so thata relatively l-ight or heavy stock, vmay be used, as desired, as may bebest suited for the particular character of plowing or cultivationto beperformed. For the accomplishment of the foregoing and such otherobjects as may hereinafter appear, the invention consists in a bed orshoe having features of construction hereinafter particularly describedand then sou ht to be clearly defined by the claims, re erence being hadto the accompanying drawing forming a part hereof, and in which Figure 1is a side view of a plow embodying the invention.

Fig. 2 is a horizontal section on the line 22 of Fig. 1.

Fig. 3 is a front view of the bed or shoe Fig. 4 is a rear view withthe'plow point.

or blade attached and the stock in section;

Fig. 5 is a perspective view of one form of plow point or blade,detached.

In the drawing the numeral 1 designates the face-plate of the bed orshoe which is l'ormed with vertically extendingslots 2 and 3 for thereception of a bolt 4 for attachment of a point or blade 5 to theface-plate and-to permit vertical adjustment of the point or blade tocompensate for its wear. The bolt 4 also passes through the stock 6which may be of any approved type, the stock beingIformed with slols 7and 8 corresponding'to the slots 2' and 3 of the faceplate so that thebolt may be adjusted correspondingly to the adjustment of the plowpointer blade, and may be shifted from the Specification of LettersPatent.

position shown in full lines to the position shown in dotted lines, inFig. 1, as .the plow point or blade wearsand is lowered to workingposition. From the rear of the face-plate extends a landside-plate orwing 9 which is formed in one face with a recess 10 to receive alandside extension plate 11 which has at its upper forward portion anoverhanging part 12 which bears against the rear inclined edge of thelandside wing 9 so that when the landside extension plate is attached tothe landside wing by a bolt '13the landside extension plate is heldrigidly to the landside wing and against any movement relatively there-'.to.

The rear of the face-plate l at a point spaced from the landside wing 9is formed with an enlargement 14 which in conjuncforms a vertistoclc 6,and bolts 16' passed through-openings in the landside wing, theenlargement the other, to suit the work of cultivation to be performed.For the purpose-of affordplow point or blade, and incidentally affordinga wearing surface, a plate or offset 17 is located at the side of theface-plate and landside wing so as to project forward of the face-plateand have the edge of the plow point or blade abut against the same as indicated in the drawing and thus prevent the plow point'or blade fromturning or twisting on the bolt 4 which attaches it to the face-plate ofthe bed or shoe. This abutment may be cast integral with the bed orshoe, or attached thereto by the-bolts which attach the bed or shoe tothe stock.

The attachment-bed or. 0e described makes it possible to conve one typeor style of plow into another by merely substituting one stock foranother to suit the .ing a retainlng' or bracing abutment for the Onebed or shoe dtlier efore answers for different plows an,

admits of attachme'ntto many of the different standard types of metalstocks now in use.

Having described my invention and. set forth its merits, what I claimis:

1. A plow blade supporting attachment comprising a bed-plate provided atone side with a rearwardly extending land-side wing and an off-setprojecting forward of the bed-plate on the land side, the' bed-plate be:

ing formed with a socket made in its rear face to receive a plow-stock,the Wall of the 7 socket next to the land-side and the oppositewallserving to brace the stock.

2. A plow blade supporting attachment comprising a bed-plate provided atone side with a rearwardly extending landside wing formed with a recessin one face, a landside' with a rearwardly extending landside wing, alandside extension plate having an overhanging portion at its upper edgeoverlying the upper edge of the landside Wing, and means for securing.the extension-plate to the landside wing.

In testimony whereof I affix my signature in presence of two witnesses.
